Geological time scale — 4. Geological maps. Absolute age dating deals with assigning actual dates in years before the present to geological events. Contrast this with relative age dating, which instead is concerned with determining the orders of events in Earth's past. Scholars and naturalists, understandably, have long been interested in knowing the absolute age of the Earth, as well as other important geological events.

How is Earth's Age Calculated?
How is Earth's Age Calculated? | Live Science
The calculation of radiocarbon dates determines the age of an object containing organic material by using the properties of radiocarbon also known as carbon , a radioactive isotope of carbon. Radiocarbon dating methods produce data based on the ratios of different carbon isotopes in a sample that must then be further manipulated in order to calculate a resulting "radiocarbon age". Radiocarbon dating is also referred to as carbon dating or carbon dating. Calculations of radiocarbon dates are typically made based on measurements from beta counting devices or from accelerator mass spectrometers AMS. There are several possible sources of error in both the beta counting and AMS methods. The calculations to be performed depend on the measurements taken based on the technology used, since beta counters measure the sample's radioactivity , whereas accelerator mass spectrometers AMS determine the ratio of the three different carbon isotopes in the sample.
How can you use carbon dating to find the age of a fossil
Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues. When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon
To find the years that have elapsed from how much Carbon 14 remains, type in the C percent and click on Calculate. Chapter 4: What about carbon dating? Most people find the subject of radiometric dating too technical to understand. Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
